Abstract :
The class E amplifier with a clamped switch peak voltage using a transformer and a diode is proposed, analyzed, simulated and tested. The peak switch voltage is clamped without producing a significant power loss. Design equations are derived for components and the output power. The effect of the leakage inductance of the transformer is examined with PSpice simulation. The experimental results for a prototype circuit are presented.
